Any year being given, either before or after Christ, Old or New Style, find the century at the top of the Table in page 72, and the odd years in the middle column. The square of intersection contains the Dominical Letter for the year. Then look for the given day of the month in the Table above, and the day of the week will be shown in the column under the Dominical Letter at the right hand. If the given year be a Leap Year, and the month January or February, it must be looked for under the head January, LY, February, LY. A leap year after Christ is marked by a dot on the right hand; one before Christ is marked on the left. II. METEOROLOGICAL INFORMATION. I. NATURAL HISTORY OF THE WEATHER.* [See American Almanac for 1831, p. 100.] DEW AND HOAR FROST. ANOTHER visible evidence of the fact of aqueous vapor pervading the transparent atmosphere, is the appearance of Dew. Nothing can be stronger than the conviction produced by observation, that this fluid has its principal source in the atmosphere. It is a little remarkable, that while this origin has been granted with regard to rain, whose formation is carried on in regions generally far beyond our range of vision, and at elevations which we have no convenient means of visiting, it has been denied with regard to dew; though this latter, produced upon the surface of our planet, is never out of our reach, and consequently may be subjected to our examination whenever we are disposed to investigate its production, or observe its subsequent changes and conditions. Dew, on its first formation, appears sprinkled over the surfaces of some bodies in small irregularly-shaped flat spots, or attached to the filamentous parts of others in minute globules, of colorless transparent fluid. As the dewing process continues, these increase in size, and frequently running together, escape from sloping and perpendicular surfaces, in little descending streams. The globule of dew, in accordance with the popular notion that "It droppeth like the gentle rain from Heaven," has been called a dew-drop; but though the name be continued, the descent is now considered altogether imaginary. No dew-drop has ever yet been remarked to form without contact, nor to fall except from some substance to which it had been previously attached. The touch of the minutest thread of the finest spinner is sufficient to start it into being, and to hold it, *The first section of the following article is taken from the Companion to the British Almanac, for 1831. |
